639031 divided by 29 
The aim is to understand the frequency of 29 in 639031.

Let's proceed to step 1:
6 divided by 29 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 29

Advancing to step 2:
When dividing 63 by 29, we get 2 with a remainder of 5.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 58 from 63 and we're left with 5.
Fetch the next digit (9) from the dividend, attach it to 5 and continue: 59 / 29

Advancing to step 3:
29 can be fit into 59 2 times, resulting in a remainder of 1.
The next digit of our result is 2. 
Result so far: 22.0
If we take 58 away from 59, we end up with 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 29

Moving on to step 4:
If we divide 10 by 29, we get 0 and a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 220.0
If we subtract 0 from 10, we get 10.
Grab the next digit (3) from the dividend, add it to 10, then carry on: 103 / 29

Moving on to step 5:
29 goes into 103 3 times with a remainder of 16.
The next digit of our result is 3. 
Result so far: 2203.0
Subtract 87 from 103 to get 16.
Take the next digit (1) from the dividend and append it to 16, then repeat: 161 / 29

Going ahead to step 6:
29 can be fit into 161 5 times, resulting in a remainder of 16.
The next digit of our result is 5. 
Result so far: 22035.0
Subtract 145 from 161 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 7:
The number 29 fits into 160 5 times, leaving a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 22035.5
Subtract 145 from 160 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 8:
If we divide 150 by 29, we get 5 and a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 22035.55
If we take 145 away from 150, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final outcome is 22035.55, with a leftover of 0.005.
